The Council for Watershed Health established a cooperative program to provide watershed-specific native propagules for use in restoration and revitalization projects within the watersheds of Southern California. The program promotes water conservation as well as protection and enhancement of the ecological health of native plant populations within Southern California through the use of locally-native genotypes in landscaping and restoration projects.

Striving to nurture an ethically-obtained, reliable supply of local native plants for public landscaping and residential gardens.
